However, the potential of BiFeO₃ as a photovoltaic material is limited due to its low photocurrent density and consequently low power conversion efficiency. Herein, a novel ferroelectric photovoltaic architecture based on the (Pr, Ni) gradient-doped BiFeO₃-based thin film coupled with Au nanoparticles layer has been designed and fabricated. The experimental results and analysis show that this photovoltaic architecture exhibits extremely large photocurrent density (5.19 mA/cm²), which is about 472 times larger than that of pure BiFeO₃ film (11 μA/cm²) and about 10 times larger than that of the conventional (Pr, Ni)-doped BiFeO₃ film (0.54 mA/cm²). The enhanced photocurrent density should be attributed to the multifactorial coupling effect in this photovoltaic architecture, including the built-in electric field formed by the gradient distribution of oxygen vacancies, the flexoelectric effect and Local Surface Plasmon Resonance effect of Au nanoparticles.</p></div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":"35 31","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142587840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Dy³⁺ doped BPTLAND glass amorphous form was confirmed by an analysis of powder X-ray diffraction. Using EDAX and SEM analyses, the chemical compositions and surface morphology of the prepared glass were examined. FTIR and Raman analysis identified the presence of borate and phosphate groups. Absorption spectroscopy examined the glass’s optical characteristics, with a refractive index of 1.4 at 2 eV and an optical band gap found to be an indirect band gap. The band gap is determined by the intercept of the tangent to the x-axis, which is 2.80 eV. Photoluminescence research revealed dominating emission peaks at 573 nm wavelength. The CIE chromaticity coordinates of the prepared glass were found to exhibit daylight, are <i>x</i> = 0.3647, <i>y</i> = 0.4762, and the Correlated color temperature was found to be 4823 K. The produced glass’s ferromagnetic characteristics were confirmed using VSM analysis to evaluate the hysteresis loop’s retentivity and coercivity of magnetic behavior. Using galvanostatic charge–discharge (GCD), electrochemical impedance spectroscopy (EIS), and cyclic voltammetry (CV), the electrochemical properties of the generated electrodes in a 5 M KOH electrolyte were examined. After 2000 cycles, the glass electrode doped with Dy³⁺ (BPTLAND) displays the greatest specific capacitance value (258.12 F g⁻¹ for GCD). Scan rate behavior was unique and exhibited redox behavior. In addition, the anodic–cathodic peak difference increases with increasing peak density as the scan rate increases, suggesting that the material is quasi-reversible. The flawless double capacitance characteristic of Dy³⁺ doped BPTLAND glass was demonstrated by each CV, which showed a regular rectangle. The charge transfer resistance for this electrode was found to be 34.53 (Ω cm²) whereas the ohmic resistance is 14.21 (Ω cm²). The working electrode’s capacity for long cycling performance was consistent CV curve after 5000 cycles indicating the electrode maintains good structural and electrochemical stability over prolonged cycling.

The actual operating temperatures were verified through electro-thermal equations and electrifying-tensile tests. Additionally, vacuum heat treatment experiments were performed to simulate heat generation in low-oxygen environments. Analysis showed Pd diffusion depth of approximately 5 microns, indicating that under low-oxygen conditions, copper and oxygen tend to form cubic copper(I) oxide.
